The 500 Cities project is a collaboration between CDC, the Robert Wood Johnson Foundation, and the CDC Foundation. The purpose of the 500 Cities Project is to provide city- and census tract-level small area estimates for chronic disease risk factors, health outcomes, and clinical preventive service use for the largest 500 cities in the United States. These small area estimates will allow cities and local health departments to better understand the burden and geographic distribution of health-related variables in their jurisdictions, and assist them in planning public health interventions. See bottom of page for the note for data users. Learn more about the 500 Cities Project.

Notice to 500 Cities Data Users:

In the process of updating the 500 Cities data, CDC found a data discrepancy in the published 500 Cities data for the 2014 city-level obesity crude prevalence estimates. This happened when reformatting the SAS data file to the open data format. The small area estimation model and code were correct. This data discrepancy only affected the 2014 city-level obesity crude prevalence estimates on the Socrata open data file, the GIS-friendly data file, and the 500 Cities online application. This error was corrected on December 1, 2017 with the upload of the new 2015 data estimates. If you previously downloaded the affected Socrata and GIS-friendly city-level data files listed below, you may download the corrected versions from the archived files on Socrata.
